Query: NC_010382:1020516 Lysinibacillus sphaericus C3-41, complete genome
Lineage: Lysinibacillus sphaericus; Lysinibacillus; Bacillaceae; Bacillales; Firmicutes; Bacteria
General Information: Lysinibacillus sphaericus C3-41 was isolated from a mosquito breeding site in China. This organism is highly toxic to Culex species of mosquito. Lysinibacillus sphaericus, formerly Bacillus sphaericus, is a common environmental organism which produces an insecticidal toxin similar to that produced by Bacillus thuringiensis. Lysinibacillus sphaericus produces two proteins during sporulation which accumulate in parasporal crystalline inclusions. These proteins bind in the gastric cavitiy and midgut of the larvae causing disruption of feeding by the infected host and death.
Subject: NC_010001:404066 Clostridium phytofermentans ISDg, complete genome
Lineage: Lachnoclostridium phytofermentans; Lachnoclostridium; Lachnospiraceae; Clostridiales; Firmicutes; Bacteria
General Information: Isolated from forest soil near the Quabbin Reservoir in Massachusetts, USA. This organism plays an important industrial and ecological role in the anaerobic fermentation of cellulose and produces economically significant levels of acetate and ethanol. This genus comprises about 150 metabolically diverse species of anaerobes that are ubiquitous in virtually all anoxic habitats where organic compounds are present, including soils, aquatic sediments and the intestinal tracts of animals and humans. This shape is attributed to the presence of endospores that develop under conditions unfavorable for vegetative growth and distend single cells terminally or sub-terminally. Spores germinate under conditions favorable for vegetative growth, such as anaerobiosis and presence of organic substrates. It is believed that present day Mollicutes (Eubacteria) have evolved regressively (i.e., by genome reduction) from gram-positive clostridia-like ancestors with a low GC content in DNA.
